What is a Guava Tree?

Whether single or multi-trunked, the guava tree is an easy tree to care for. It can be treated as a large shrub or as a small tree, with a lifespan of 30-40 years.

It’s known as common guava, but may also be called the lemon guava or yellow guava tree. As the fruit’s size is comparable to that of an apple, it may also be called an apple guava tree. But the guava scientific name is Psidium guajava. Various languages around the world have their own names as well, with the Spanish referring to it as guayavo, the Portugese goiaba, and so on.

Native Area

The plant is native to South America.

In its native range from southern Mexico into Central America, it can grow as tall as 30 feet in height. But where does guava grow? Widely grown in temperate regions, psidium guajava can be found in Asia, the southern United States (especially in Florida), and Australia as well as its native range in Mexico and Central America. 

Characteristics

The plant features fleshy evergreen leaves and it can produce fruits and flowers.

Like many tropical plants, it has fleshy leaves that are evergreen in the right climate. They are aromatic when crushed and form in pairs opposite one another on the stem. These lovely leaves may be the inspiration for every kid’s drawing of a leaf with a very distinct vein pattern. Typically, the leaves range between two and a half to six inches in length.

The tree’s bark is distinctive as well. Thin and smooth, it flakes off to expose a pale green underneath the copper-brown exterior. Young branches are a bit downy to the touch until their bark fully dries out, almost looking as though they have a light fuzz on their surface.

Five-petaled flowers may appear up to twice a year, depending on the climate. For cooler climates, they will spring into existence in late spring, but in tropical regions may reappear in the fall. These white-petaled flowers have up to 250 stamens clustered together in the center. While they shed their slightly-fragrant petals quickly, the fruit often has remnants of the stamen cluster at its base as it forms.

The fruit can be yellow to light green in color. It may be round, pear-shaped, or oval. Its flesh can be white, pink guava fruit, or red in hue, depending on the cultivar. Most of its seeds are hard to chew, although a few rare cultivars may have softer seeds. Flavor-wise, it’s described as a combination of mango, strawberry and pear.

Varieties

There are many varieties of guavas, and they are commonly called after the color of the fruit flesh. These include ‘White’, ‘Lemon’, ‘Pink’, ‘Strawberry’, and ‘Tropical Yellow’. You can order a ‘White’ guava tree online from the Epic Gardening shop.

Planting

How do you get a guava off to the right start? Let’s talk about the best ways to get your guava plant set up for greatness.

When to Plant

The plant will perform best if planted during warmer months.

Guavas can be planted at virtually any time of year in tropical zones, but do best in the warmer months. Early spring when it’s just starting to warm up is a good time, as it gives the tree time to stretch out its roots underground before hot weather sets in.

If you’ll be growing your guava tree in a container and bringing it indoors for the winter, you can start anytime provided that the conditions are relatively warm. Aim for temperatures that are above 45°F, and preferably above 50°F (7-10°C).

Where to Plant

Set the plants on a location that receives full sun.

While you’ll need to make sure your tree has full sun and another tree for pollination purposes, you’ll also need to keep them separate. Guavas should be placed at least 33 feet apart when possible but can be as close as 16 feet if necessary.

Place your guava trees in sunny, well-lit locations as they require full sun. Provide a place that is at least somewhat protected from wind, if possible, whether by fencing or another windbreak. Your small guava tree will need that protection to develop, and older guava trees can be sensitive to cold winds too.

Guavas can be planted as espalier trees on cordons. However, don’t place other plants beneath them, as exudates from their root system tend to kill off weeds or other ground covers at the tree’s base.

How to Plant

An overhead shot of a person's hand planting a sapling on rich soil in a well lit area outdoors
Set up the plant in a hole that is at least twice the width of the root ball.

When planting a young tree, you want to dig a hole that’s at least twice the width of the root ball, wider if possible. This allows you to break up any hard soil that might slow early root development. Use the blade of your spade or shovel to loosen the sides of the planting hole as well. Amend the soil with compost if needed, but try to avoid large amounts of fertilizer, as they can cause burning to young and tender root systems.

Ensure that your soil is well-draining by filling the hole with water and waiting to see how long it takes to drain. If it takes longer than a few minutes, dig down a couple more feet and add perlite or other soil looseners to speed drainage.

Place your tree in at the depth at which it was originally planted. Do not set it any deeper, as that can be a potential hazard for the trunk. Fill with the original soil, amended with compost if desired. Mulch to a depth of three to four inches around the tree, making sure to maintain at least a four to six-inch clear space around the trunk itself. 

How to Grow

Let’s talk about the best way to keep your guava tree growing and producing!

Light

The plant prefers lots of full sun exposure and warm conditions.

Your guava tree is tropical. It needs lots of full sun and warm conditions to truly thrive and produce. Guava trees require a minimum of six hours of sun per day but prefer eight to ten hours.

Water

The plants require at least once or twice a week of watering, a soaker hose provides slow watering,

While your guava is somewhat drought-tolerant once established, that’s not true when it’s young. Young trees should be watered every other day through their first year of growth, except in the winter months when temperatures are cooler and the tree is dormant. 

Somewhat shallow-rooted, the majority of your guava’s moisture will come from the upper layers of soil. As the upper portion dries out quicker than deeper soil would, providing mulch can help keep moisture from evaporating as quickly. Placing a soaker hose underneath the mulch allows you to water at a slow trickle that won’t harm the root system.

Even older trees may need a slight boost to the watering regimen during fruit production. Check the soil beneath the mulch to see if it’s moist before watering. Usually, once to twice a week is fine for established, mature trees.

Soil

Dirty hands hold a handful of fresh, dark brown fertile soil against a backdrop of earthy ground.
Use a rich soil that has plenty of organic material and good drainage.

Rich soils with high amounts of organic material are preferred by your guava, but it can grow in a wide range of soil types. Avoid heavy clay soils when possible, as they aren’t conducive to good root development. Good drainage is key, as this tree doesn’t tolerate standing water well.

A pH range of 5-7 is best for these plants.

Temperature

The plants perform best in hardiness zone 9 to 11.

If you’re planting it in your yard, you should be in growing zones 9b-11 to ensure its safety during the winter months. People growing them in containers will need to bring them indoors once the weather dips into the 40s (~4°C) but will still need to provide lots of light.

They can tolerate heat but perform at their best in temperatures between 65 and 90°F (18-32°C). If the temperature drops below 30°F (-1°C), the tree is at risk of severe damage.

Fertilizing

A hand covered in dark soil holds bright yellow fertilizer granules.
Once the plants are established, apply a slow-release fertilizer every other month.

For the first year of growth, fertilize monthly with a balanced complete fertilizer during the growing season. Skip fertilizing from November through January, as the tree will be dormant. These trees like extra magnesium and iron in their food, so check your fertilizer label to ensure there’s some in there.

To promote good fruit development once pollination has happened, you can raise the level of potassium slightly if you’d like, but it’s just not necessary if you’re consistent with the application.

Once your guava tree is established and past its first year, provide more fertilizer per feeding but cut it back to every other month. A slow-release blend is still preferred, and granular types are ideal. Evenly scatter it across the soil over the root area. You can work it into the surface of the soil if you wish.

Maintenance

Maintenance involves pruning by trimming off sucker shoot and maintaining its size.

If you are growing your guava in a shrub-like form, you don’t have to prune away the lower sucker shoots. However, most prefer to keep them in tree form, so they don’t spread out of control.

When removing sucker shoots, take them off as close to the base of the tree as possible. Light pruning of the canopy will open it up to more sunlight and airflow. Guava fruit develops on new shoots from mature wood, so be careful not to remove all new growth.

If maintaining a tree to a certain height, do heavy pruning in the late winter every other year to keep it in the desired height range. Try to leave some older wood in place. Be sure to cut above any visible budding points when possible, as that’s where future growth will develop.

A single-trunked tree with at least three or four lateral branches will form a nice, appealing canopy shape. 

Guava tree pruning should also be done to remove damaged or diseased branches as needed. Whenever pruning, use sterilized pruning shears or loppers to prevent disease spread.

Propagation

Propagation can be done by seeds, root cuttings or grafting techniques.

Guava seeds can remain viable for a long time. Soak your seeds in warm water for at least 24 hours before planting, although you can leave them in the water for up to a week if you need to. Seeds should be planted in moist, warm soil and kept damp throughout germination. This is the most reliable method of propagation if you only have one variety of guava. If you’re growing multiple cultivars, cuttings are best.

Root cuttings are the next option for propagation. At least two to three feet from the tree, cut off a section of root that’s at least five inches in length. Place it in warm, damp soil and keep it moist. New shoots should start appearing within three to four weeks.

Half-hard cuttings from branches can also be rooted. Remove a ring of bark at the cutting’s base and apply a rooting hormone before planting. These should also be kept moist and warm.

Harvesting

When is guava ripe? Guava fruit ripens in its second to fourth year. You should pick your guava fruit when it’s full-sized and has become slightly soft and aromatic. But it can be harvested prior to full ripeness, as it’ll continue to ripen even after it’s harvested. 

If harvesting fruit early, be sure to select guava fruits that are of a good size, leaving small fruit to continue to develop. Most guava fruit lightens in color as it approaches ripeness, so early harvests should be a light green in hue with slightly firmer skin. Place your harvested guavas in a paper bag with an apple or banana, as the ethylene the banana or apple emits will ripen your fruit faster.

When picking, try not to yank on the tree so as not to damage branches. Instead, use a sterilized pair of pruning shears to snip through the wood above the fruits. This protects both your produce and your tree.

Storage

The fruits can be stored fresh, as jelly or jams, frozen and canned.

Ripe guava fruit can be refrigerated for five to seven days. Green fruit can be stored for up to three weeks in the refrigerator but should be checked regularly to remove fully ripened fruit from the green fruit. Guava fruits are great in Cuban food, with fried plantains, and in empanadas.

To store your fruit for longer periods, scoop out the soft inner flesh of the fruits and compost the rind. The flesh can then be frozen or canned as a jelly or jam. Making guava syrup is also optional. It can be dehydrated as a pulp on a drying sheet and stored that way as well.

Common Problems

What problems may you encounter when growing your Psidium guajava? Let’s talk about that.

Growing Problems

Growth issues usually stem from overwatering, over fertilization improper pruning and saline soils.

Keep lawns back from the root region of your guava trees. While grass is one of the few things that can somehow manage to grow underneath your guava, any damage from lawnmowers or weed whackers to the trunk can put it at risk of disease.

Similarly, if your lawn is even near the root system, be cautious about fertilizing. Lawn fertilizer often has high nitrogen levels, which can cause your tree to produce lots of foliage and little fruit. As the roots often extend out past the tree canopy, limit your lawn fertilizing within proximity of the tree.

Overwatering can cause many issues, root rot being among those. Be sure your soil is well-draining.

For home growers, keep your guava trees at ten feet or shorter when possible. The weight of the fruit combined with any serious wind can make it unstable, and you don’t want it to fall over.

Leaf tip burn or browning has been documented in areas of saline soils, such as those near coastlines. While this typically is not severe enough to cause lasting damage, it’s something to be mindful of.

Pests

The fruit bearing plant is home to a number of insect pests.

Fruit flies are a common pest. In Florida and other parts of the southeast US, this will be the Caribbean fruit fly; in the southwest US, it’s the Mexican fruit fly. Harvest before the fruit is fully ripe to prevent the Mexican and Caribbean fruit fly. Pick up any fallen fruit, and use fruit fly traps as needed to reduce their numbers.

The guava moth (Argyresthia eugeniella) lays eggs on your tree’s leaves. The larvae tunnel into fruit and chew holes in the leaves. These can be treated with a bacillus thuringiensis (BT) spray. This moth is typical in the southeast US, particularly Florida.

Red-banded thrips will cause browning of fruit rinds and defoliation of your tree. Neem oil and sticky traps can keep these at bay.

The guava whitefly (Metaleurodicus cardini) also feeds on guava leaves. Spraying the tree three times a year with horticultural oil will reduce their numbers.

A number of types of scale insects, including some mealybugs, are fond of guava wood and leaves. Neem oil or horticultural oil can reduce their spread. Small infestations can be treated by hand with a cotton swab dipped in rubbing alcohol to remove the pests.

Finally, root knot nematodes can be particularly harmful to your guava. Reduce their numbers by applying beneficial nematodes to the soil around the trunk and across the root area.

Diseases

Algal leaf spot, anthracnose and root rots are common diseases of the plant.

Red alga, also called algal spot or algal leaf spot, is caused by the fungi Cephaleuros virescens. This condition creates purplish-brown spotting on leaves and can, if severe, cause defoliation and lowered fruit production. Another common fungal problem is anthracnose.

Finally, fungal root rots can develop in overly-wet conditions. Ensure the soil drains readily to prevent this from occurring. 

Frequently Asked Questions

How big do guava trees get?

In tropical regions, guava trees can grow up to 20 or 30 feet. Most home growers keep theirs at 10 feet or shorter for ease of harvest.

How fast do guava trees grow?

Surprisingly fast, all things considered. If you plant from seed, you’ll start harvesting fruit from your guava trees within two to three years, with maximum harvests of guava fruits between four to fifteen years after planting. That’s significantly shorter than many other fruiting trees!

Where is the best place to plant a guava tree?

Plant guava plants in an area with morning sun, afternoon shade, and rich, moist soil. Also, provide proper spacing between your tree and other plants.

Are guava trees easy to grow?

Relatively! If you provide these fruit trees with what they need, they’ll do just fine.

Do you need two guava trees?

Most of the time, yes. However, pineapple guava – among others –, does require a male and female tree for pollination. Sometimes hand pollination is necessary too.

How long does guava tree live?

The full life span of a guava tree is about 30 to 40 years.

Are guava roots invasive?

Thankfully, no! Plant away.
